Dr. Conley explained “dicamba will be limited to those growers that have this extra level of certification. Most likely it will drive the application of these products to custom applicators. For a grower it may cost them more (they have to pay someone to apply it); but it will shift the application liability to the certified applicator.”

The EPA’s hope is that the movement to certified applicators and subsequent increased training on these products will reduce the incidence of off target movement of dicamba products in 2018.
